Calliope

Calliope is one of the Muses of Greek mythology. She is the mother of Orpheus by Dream.

A writer named Richard Madoc took her captive, and as a result was given great ability in writing, but Calliope calls upon the trio of witches known by many names, including the the Furies, the Kindly Ones, and the Gracious Ladies, for help. They direct her to her old lover Morpheus, but he is currently also imprisoned.

After his own release, Dream goes to rescue Calliope. Madoc, however, complains that without her, he will have no ideas, so Morpheus causes him to experience an overabundance of ideas. He cannot concentrate on any one thing and is nearly driven to madness. Finally, Madoc frees the Calliope, who mercifully asks Dream to release Madoc from his torment. Dream complies.
